Qualified Materials

Overview

Only qualified materials that have been approved according
to Section 106 of NJDOT Standard Specifications may be used for
construction or maintenance of New Jersey's transportation infrastructure.
NJDOT maintains databases of qualified materials for materials that
are required to be on a qualified products list (QPL) for use. If
a material is required or permitted to be on a QPL, the QPL is referenced
in the materials specification in the 2007 NJDOT Standard Specifications.

NOTE: Not all materials specified
by NJDOT are required to be from a QPL. For those materials that
are not required to be on a QPL for use on construction projects,
the material is approved according to the Materials Questionnaire
process as detailed in Section 106 of NJDOT Standard Specifications.

Qualified Materials Databases

There are databases for the following materials/products:

1. Standard Materials Qualified Products List

The Standard Materials QPL is for materials other than
aggregates, electrical materials, or intelligent transportation
systems that are required in Section 900 of the NJDOT Standard
Specifications to be on a QPL prior to use by the Contractor.
Following is a list of the materials on the Standard
Materials QPL:

2. Aggregates Qualified Products List

DOT maintains a separate Aggregate
Producers database containing producers and corresponding
sizes of aggregate materials that are qualified to supply DOT
projects. This database is a compilation of geologic evaluations
and quality tests performed on various aggregate sources that
may supply aggregates to DOT. The data reflects average test values
of the latest results. It does not reflect the legal qualification
of the producer to supply materials to DOT sponsored projects.
Supplemental Specifications for an individual project and other
contract documents should be reviewed to determine if a producer
is legally qualified to supply material to a project. Data changes
are noted in the remarks column. Terminology can be found on a
glossary
page. This database was correct when developed, however, producer's
materials are subject to change and all aggregate sizes are subject
to field approval at the time of use.

Materials Approval Procedures (MAP)

Materials Approval Procedures (MAP) have been developed
for materials that are required to be on the QPL prior to use. A
standardized MAP was adopted for each type of material as the approval
process is specific for each type of material.

New Technologies and Products

Non-Standard items may be examined
by NJDOT and accepted for implementation for use in roadway or bridge
design. These materials do not refer to a standard specification.
Non-standard items are put through a process of demonstration and
evaluation before they are accepted for potential use in future
designs. See New Technologies
and Products.
